LOG-HAUL SHOE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, Nmns J .ANTZEN, a citizen of the United States,residing at Victoria, in the Province of British Columbia and Dominionof Canada, have invented new and useful Improvements in Log-Haul- Shoes,of which the following is a specification.

An object of the invention is to provide a shoe, for use in logging, forconveying a leg from one place to another.

The invention embodies, among other features, a device for connectionwith a chain or the like, operable in the usual slots or chutes used inconnection with logging, the log being received upon the shoe and heldin position thereon as the shoe is advanced along the slide, the shoebeing so constructed that it will be prevented from turning sidewise andalso prevented from digging or catching in the side of the slide.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specification, and inwhich similar characters of reference denote corresponding parts in allthe views, and in which:

Figure 1 is a perspective view of the shoe showing the same attached toa chain; Fig. 2 is a bottom plan view of the shoe as shown in Fig. 1;Fig. 3 is a vertical longitudinal sectional view, taken adjacent one ofthe gripping members; and Fig. 4 is a perspective view of one of thegripping members. Fig. 5 is a perspective view of one of the securingmembers,

Referring more particularly to the views, use is made of a shoe body 10,preferably made of an integral iece of material, and having a pluralityof upwardly extending prongs 11 formed on the upper side thereof, aplurality of teeth 12 being arranged to extend from the under side ofthe body 10, adjacent one end thereof. The shoe body 10 is rovided withvertically extending slots 13 1n which are mounted gripping members 1 1,having their lOWer ends terminating in teeth 15 extending downwardlyfrom the under side of the body 10, the upper ends of the grippingmembers lt terminating in heads 16. The slots 13 are made sufficientlylong to easily receive the gripping members 14 and when the grlppingmembers have been inserted therein, the same are slid for- Patented Oct.8, 1912.

wardly in the slots to the desired position, after which suitableL-shaped securingmembers 17 are mounted ,upon the shoe body 10 with theforward depending ends of the securing members engaging the rear edgesof the gripping members 141, bolts 18 being provided to extend throughthe securing members 17 and to extend into the shoe body 10 to securethe members 17 in rigid position on the shoe body, thus also rigidlysecuring and locking the gripping members 141 on the shoe body. The shoebody 10 is provided with a series of openings 19, adapted to receive thebolts 18, the openings being arranged in alincment to permit ofadjusting the securing members relatively to the gripping members 1 1.

In the use of my device, the shoe body 10 is mounted upon a chain 20with a horizontal link 21 of the chain arranged beneath the shoe bodyand having an end thereof abutting against the teeth 12 formed integralwith the shoe body. The gripping members 14 are now inserted in theslots 13 and are pushed forwardly therein until the teeth 15 thereofgrip the other end of the horizontal link 21, after which the securingmembers 17 are mounted on the shoe body with the forward ends thereofengaging rear edges of the gripping members 14;. The bolts '18 are nowmounted to extend through the securing members 17 and into a pluralityof the openings 19 in the shoe body, and when this operation has beencompleted it will be seen that the gripping members 1 1 lock the shoebody to the link 21 of the chain 20 and the securing members 17 lock thegripping members 14 in rigid position on the body, the shoe body beingnow ar ranged to receive a log or an end of a log 011 the upper sidethereof, the log being held in position on the shoe body by the prongs11 on which the log reposes and which firmly grip the log and preventthe same from becoming unseated.

It will be readily understood that any number of log haul-shoes, such asdescribed, can be adjacently mounted on a single chain with portions ofthe log reposing on different log haul-shoes, and it will be readilyseen that when a log is mounted upon the log haul-shoes, as mentioned,the log will be prevented from turning sidewise, due to the prongs 11and will also be prevented from digging or catching in the side of theslot or chute in which the chain 20 is mounted to operate.

Having thus described my invention, I claim:

1. In a log haul-shoe, the combination with a shoe body, of prongsextending upwardly from the upper side thereof, teeth depending from theunder side of the shoe body, gripping members mounted to slide on theshoe body, and securing members mounted on the shoe body and engagingthe gripping members to retain the same in rigid position on the shoebody.

2. In a log haul-shoe, the combination with a shoe body, of prongsformed therewith and extending upwardly therefrom, teeth formed on theunder side of the shoe body and depending therefrom to be engaged by thelink of a chain, gripping members mounted to slide on the shoe body andterminating at their lower ends in teeth adapted to grip the link of thechain, heads formed on the said gripping members at the upper endsthereof, securing members adjustably mounted on the shoe body to engagethe said gripping members, and bolts for connection with the saidsecuring members and the said shoe body for retaining the securingmembers in rigid position on the shoe body.

3. In a log haul-shoe, the combination with a shoe body, of prongsextending up wardly from the upper side thereof, teeth depending fromthe under side of the shoe body adjacent an end thereof, grippingmembers mounted to slide on the shoe body, and means for retaining thesaid gripping members in rigid position on the said shoe body.

4:. In a log haul-shoe, the combination with a shoe body, of prongsformed thereon, teeth formed on the shoe body and depending therefrom,gripping members mounted to slide in slots in the said shoe body, headsformed on the, gripping members and extending upwardly from the shoebody, teeth formed on the gripping members and extending downwardly fromthe shoe body, L-

shaped securing members adjustabiy mounted on the shoe body and engagingthe said gripping members, and bolts for connecting with the saidsecuring members and the said shoe body for retaining the said securingmembers in rigid position thereon.

In testimony whereof I afiix my signature in presence of two witnesses.
